If you’re going to be shallow about it, Paul Giamatti and Rosamund Pike might seem like a slightly odd pair of movie lovebirds. However, the love affair between their characters in “Barney’s Version” hasn’t aroused any of the complaints Seth Rogen regularly gets when his movie character gets lucky with a beautiful woman. No offense to Rogen, but maybe that’s because Giamatti gets a pass for being an extraordinarily brilliant actor — who, as it happens, just picked up a well-deserved Golden Globe for his performance in this very film — and Pike gets points for having the sense to work with him, not to mention for being rather extraordinary herself.

In fact, the pair have some things in common. Pike’s parents are accomplished serious musicians and she is an Oxford Graduate. Paul Giamatti’s father was the noted Yale University President and Commissioner of Baseball, A. Bartlett Giamatti. Naturally, the younger Giamatti is himself a graduate of Yale. Both have also been busy working actors for some time. After “American Splendor,” “Sideways,” and — on a more heroic level — the miniseries “John Adams,” not to mention innumerable outstanding supporting roles, Giamatti is a bonafide star. The sky is the limit for Ms. Pike, a vastly-above average “Bond girl” opposite Pierce Brosnan in 2002’s “Die Another Day,” who more recently has received a lot of notice for her very diverse roles as a less than brilliant conman’s girlfriend in “An Education” and, more under the radar but no less brilliant, as a highly educated but frustrated housewife and mother in “Made in Dagenham.”

When I and a bunch of other junket journos encountered Giamatti and Pike, they were promoting the new adaptation of Mordecai Richler’s tragicomic final novel about the life and loves of a youthful hustler and bohemian turned aging Montreal television producer and crank. For us shallow types, Giamatti bats 1000 well out of his league with three wives in the course of “Barney’s Version,” played by the lovely Rachelle Lefevre, Minnie Driver, and Pike as Miriam Grant-Panofsky, whom he actually loves. If you read my review, you’ll see that I think the film is a very mixed bag, but the performances are first rate throughout. In addition to that Golden Globe, Giamatti’s performance was praised by his colleague Ron Perlman, and easily deserves whatever accolades it may find. Pike is, as the cliche goes, luminous in a role as a really good person that a lesser actress would have rendered merely saintly and dull.

“Yes, you did,” he argued. “You tricked me into saying it on camera. She said, ‘When you became an indie darling,’ and I went ‘Well, when I became an indie darling…'” and I thought, ‘I just said those words! Goddammit, that’s on film now, forever.'”

Giamatti, a born comedian as well as a master thesp, was already breaking up the room.
